CLOTH-MEASURING DEVICE oe LOOMS.

SPECIFICATION forming part Of Letters Patent No. 743,989, dated November 10, 1903-. Application filed April 16, 1903. Serial No. 152,879. (No model.)

To aZZ whomit may concern:

Be it known that I, LEONARD M. PHELPS, a

following to be a full, clear, and exact de-- scription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to devices for measuring cloth on looms as it is taken up after being woven and is commonly known as a loom-clock.

The object of the invention is to provide a device of this character which maybe quickly and easily attached to or detached from the breast-beam of a loom and which will accurately measure and indicate the numberof yards woven by the loom.

A further object is to providea measuring and indicating device of this character which will be simple, strong, and reliable and small enough to be conveniently carried in the operators pocket when not in use and which can be manufactured and sold at small cost.

With these and other objects in view the invention consists of certain novel features of construction, combination, and arrange ment of parts, as will be hereinafter more fully described, and particularly pointed out in the appended claims.

In the. accompanying drawings,Figure 1 is a sectional View of a portion of a loom, showing the application of the invention. Fig. 2 is a top plan view of the device detached. Fig. 3 is a similar viewwith the top plate removed, showing in dotted lines the position of the parts beneath the dial-supporting plate. Fig. 4 is a front edge view of the device.

.Fig. 5 is a detail view of the spring-pawl re moved from the casing. Fig. 6 is a sectional View similar to. Fig. 1, but taken in a diderent vertical plane to show the arrangement of the yard-string, the plane of section through the indicator being denoted by the line 6 6 of Fig. l.

In the drawings, 1 denotes a portion of a loom-frame. 2 denotes the breast-beam; 3, the take-up or sand roll; 4, the auxiliary roll, and 5 denotes the cloth -roll. These part of the present invention.

6 denotes the cloth as it leaves the warp parts and the mechanism for driving the same are common to all looms and do not form a and passes over the breast-beam and down around the sand-roll and thence around the auxiliary roll to the cloth-roll, upon which it is wound.

The invention consists of a frame or oasing 7, adapted. to be arranged upon the breast beam at a suitable point and is shown in the drawings arranged on top of and hookedover the rear edge of the same.

Within the casing is arranged an indicating disk or dial 8, rotatably mounted therein, said disk or dial being provided around its periphery with an annular series of ratchetteeth 9. .On the face of the dial is arranged a circular row of numerals, which may be from l to any desired number, from 1 to 30. being shown in the drawings.

10 denotes a partition-plate arranged within the casing between and parallel with the top and bottom plates of the casing and havingadownwardly-turned edge,whichisadapted to rest upon the bottom plate, thereby forming a space between the plate 10 and the bottom of the casing. Within this. space is arranged a spring 12, having one end fixed to the plate 10 and itsopposite end projecting beyond the. edge of the disk 8 and coiled into an eye 12' and then formed into an engagingpawl 13, having a short upturned end, which is adapted to engage the teeth 9 on the disk or-dial plate 8.

14 denotes a rod or link, one end of which is booked in the coiled eye 12', and the other end is adapted to engage one arm of a bellcrank lever 15, pivoted to the plate 10, the opposite arm 15013 which extends to near the adjacent side edge of the casing, as shown.

Between the downwardly-turned edge of the plate 10 and the adjacent side of the casing is formed a channel or passage 16.

17 denotes the measuring tape or cord, commonly known as the yard-string, the same consisting of a piece of tape or string of suitable length, which is passed around the takeup or sand roll 3 and over the breast-beam 2 and having its ends passed through a block or washer 18 and then tied together. In passing over the breast-beam the tape is adapted ICO to pass through the channel or passage 16 of the casing 7. In the top plate of the casing 7 is formed a slot or view-opening 19, through which one of the numbers on the dial is visible.

In practice the indicating device is placed upon the breast-beam and the yard-string is passed around the take -up roll over the breast-beam and through the channel 16 and beneath the arm 15 of the bell-crank lever, the length of the cord being such that as each yard of cloth is Woven and taken up by the take-uproll the yard-strin g will be caused to make one revolution, and at each of said revolutions the block or washer 18 is brought into engagement with the arm 15' of the bellcrank lever 15 and rocking said lever, the opposite arm of which, through the medium of the link 14, actuates the pawl 13, which eugages the teeth on the dial-plate and turns said plate one tooth ahead, causing an increased number to be visible through the slot 19 in the top of the casing at each revolution of the string or tape.

The advantages of adevice of this character will readily be seen. It not only accurately measures each yard of cloth as it is woven on 1 the loom, but it also enables the weaver lo know at all times exactly the number of yards of cloth there is on his loom and just what time he makes on each, thereby helping him to guard against any irregularities or slothfulness. A further advantage is in the simplicity and cheapness of the device, as well as the ease and quickness with which it may be applied to or removed from any loom, being easily carried in the vest-pocket when not in use.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood Without requiring a more extended explanation.

, Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a cloth-measuring device, the combination with a traveling yard-string carrying a contact-block, of acasin g, an indicatingdial rotatably mounted in said casing,a springpawl adapted to engage said dial, a bell-crank lever one arm of which is connected to said pawl and the opposite arm of which is adapted to lie in the path of movement of said traveling contact-block, and to be engaged thereby to actuate said pawl and rotate said dial, substantially as and for the purposes described.

2. In a cloth-measuring device, the combination with a traveling yard-string carrying a contactblock, of a casing having a guide channel or passage through which said yard-string is adapted to pass, an indicating-dial rotatably mounted in said casing, a spring pawl arranged in said casing and adapted to engage said dial, a bell-crank lever pivotally mounted in said casing, a link connecting said pawl with one arm of said bellcrank lever, the opposite arm of which is adapted to lie across the guide channel or passage formed in said casing and in the path of movement of the contact piece on said traveling yard-string, substantially as and for thepurposes described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

LEONARD M. PHELPS.
